This invention relates to devices for fastoning in assembled relation forms for molding or shaping concrete structures.

This invention has for its principal object to provide a novel fastening device of the wedge type which may be employed especially with tie-wires, tie-rods and similar elements employed to hold form walls in place; which fastening device may be quickly and easily manipulated to clamp and tightly draw together the form walls so as to lool; the same in place.

This invention has for a further object to provide a novel fastening device which is a unit, that is, which is so arranged as to its parts that the same are retained in mutual operative relation both when in use and when removed from the forms.

This invention has for another object to provide a simple and effective fastening means for securing and tightening up wireties or other bendable members which are so commonly used for holding the form structures in place, and which, notwithstanding such adaptability, may also be used at will for securing tie-rods or other similar links.

Other objects of this invention, not at this time more particularly enumerated, will be understood from thefollowing detailed description of the same.

This invention is illustrated in the accompanying drawings, in which:- Y

Theuse of the novel fastening device of Serial No. 482,951.

this invention has been illustrated in the drawings in connection with a common type of concrete wall form, although it Will be understood that the same is applicable to many other specific types of forms. The wall 5 form shown comprises, laterally spaced side members 6, usually maintained in desiredspaced relation by intermediate stretchers or spacer pieces 7 extending therebetween. Battens 8 abut the outer faces of the side GU members 6, and wire ties 9 are engaged around the battens land through the form to dra-w and hold the side members into the proper positions determined by the stretchers or spacer pieces'?. The novel fastening device of this invention comprises a wedge receiving element or abutment block 10 having a longitudinal or axial opening or chamber 11 therein, and being further provided, adjacent to its outer end, with internally threaded laterally and oppositely projecting bosses 12 in which are respectively engaged set-screws 13. The said set-screws 13 thus have their biting ends 13 entered from opposite sides into the opening or chamber 11, so that the same may be manipulated to grip and hold the end of a tie means therebetween. integrally formed with and at the inner end of said wedge receiving element or abutment block 10 are laterally and oppositely projecting portions or lugs 1li having forwardly extending wings 15 overhanging the adjacent end of said wedge receiving element or abutment block 10. vThe end of said wedge receiving element or abutment block 10', between said wings 15, provides an abutment face 16 to engage the inclined face of a wedge member, as will presently appear. Formed at or near the eXtremities of said wings 15, to project inwardly from the inner sides thereof, are keeper lugs 17 for purposes subsequently herein eX- plained. The outer faces of said wings 15, and projecting portions or lugs 14 from which they spring, are provided with longitudinally, and preferably inwardly inclined, seating grooves or channels 1 8. Lateral openings 19 arel provided in opposite side walls of said wedge receiving elementor abutment block 1D adjacent to the rearward ends of said seating grooves or channels 18.

The reference character 20 indicates a wedge melnber which is arranged for longi- "5 tudinal movement between the wings 15 of 'sul said wedge receiving element or abutment block and slidingly against the abutment face 16 of the latter. lThis wedge member is so formed as to possess a longitudinal slot 21 which registers with the opening or chamber 11 of the receiving element or abutment block, so that the tie so secured and tightened may be extended through thev wedge member, where such arrangement is desired. The vertical plane face 22 of the wedge member is disposed to vabut the vform structure, while .the inclined planeface 23 is disposed to abut Athe #face 16 of the receiving element `ori-abut- `ment block. Theisilesof thewedge member lare ,provided Aalong the -verticalplane faceQS, `top onbroadened and along. the inclined .plane :tace-,23 .respectively with laterally projecting flanges 24, .24' Aand24. The lower extremitiesof xthe flanges 24 `and 24 are initially spaced apart to provide a :gap 25 through which 7.the lkeeper lugs A17-of Ithe receiving eley-meint orabutment block ma he passed, when .the wedge .member ds assem led with the Ilat- -.ter,.after which the extremity of Ythe flange 24 is bent inwardly to form a `closure .member26'for lthe gap. Said flanges bounding .the sides ofthe wedgemember thusprovide .enclosed spaces into' which thekeeper lugs 17 entend, whereby the wedge member, `while ytree for vertical movement relative to `the receiving element or abutment block when the deviis in use, is .nevertheless held -against sepanution from `said receiving element .or abutment block when Vthe device is removed from a form or not in use.

.To permit forcible driving 'of the wedge :member in use, bymcans of hammeror like blows, andn `such lnanner .as 4not to injure `or deformthe wedgemenibenthe same is provided at its upper .or wide end with astriking anvil. orboss-.QTVasfshown One manner of using V.the .novel fastening device of this invention te secureand .tighten trie-wires 9, or similar .bendable or'iiexible tying elements, isshown in Figs. 1 Vto 3 inclusive of the drawings. By this manner of use,.the tie-wire 9 is engaged about a hatten 8 at one side of the form, and its end rportions extended throughtlie form walls and yform interior, to project beyond the opposite side ofthe form. YOne such end portion is passed through an opening'inthe batten engaging said opposite side of the form, and thence through the wedge slot Q1 and openino or chamber V11 'of' the receiving elementor abuttment 'block 1'0,solas to extend "between the ?biting^ends`13 o the set-screws Said `ret-screws 13 are lthen `screwed inwardly to ni and anchor said tie-wire end portion. The other endiportion ofthetie-wire is thereupon extended through a seating groove or channel 18, and thence transversely through the openings 19 of the abutment block 10, from one side of the latter to the other, whereupon its terminal portion is helically wound, as at 28, externally around the body of said abutment block 10. In this manner both end portions of the wire-tie 9 are secured to the abutment block, this having been done while the wedge member is in updrawn er raised position. The wire-tie 9 having been thus secured, the wedge member 20 may rthereupon be driven downwardly so as to wedge between the engaged batten and abutment block, thereby drawing taut the vtie-'wire to pull the form sides home and thereafter hold the same in place.

Another .manner of using the novel fasteningfdevice with tie-wires 9 or other bendable or iexible t'ying elements, is shown in Figs. 4

und i the dnawings. In this arrangement, thestie-wire 9 is engaged about a hatten 8 at one'side of the form, and itsfend portions extended -throughfthe form to the opposite side thereof, 4one on either Vside of the `adjacent hatten. Une `end portion of -the bie wire is passed along one side of the wedge member .20-and thence along a seating groove or'channel1f8 -at one side of the abutment Ablock 10, and thencetransverscly through the latter by waiycftheopenings 19, andalong the seating grtxweorrchannel 18 at the opposite side of the abutment block ,'10 to meet the other end portion of the tie-wire which is Ipassed `along thefopposite side'fof the wedge member. The Aurleetingend,portions of said tie-wire are then :twistedtogethen as at 29, or otherwise mutually secured against separation. In this manner the tie-wire is secured in engaged re- "lation ito the abutment block 10, while the wedge member 20 is in 11p-drawn or raised position. The wire tie having been so sei'cured, the wedgemember is thereupon driven downwardly so `as to wedge between the engaged batten and abutment block, 'thereby :drawing taut the tie-wire to pull the form home and thereafter hold thesame in place. rThe Vabove described ways of using the :fastening device, it will be understood, are "illustrative of some of many different ways of securing tie-wires or other bendable or vllexibletyin'g elements to the abutment block v10.

ing form walls into and holding vthe same in place; the fastening device,-however, is not limited for such uses, since it may with advantage be also used in connection with rigid tie-rods or similar types of connectors, in

which 'ease the rods may be secured to the l end of said abutment blocks l by the gripping engagement of the opposed set screws.

As many changes could be made in the above described construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all metter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
